Installing new ceiling fan with leds. Everything is tight & getting power but the fan and light won't turn on. I changed the codes on both the remote and reciever numerous times, rewired the unit several times thinking there was a loose connection. The other lights and outlets on the same circuit are working just fine. This is the 2nd unit with this issue.
The wall switch installed in the room worked with the old fan. This is a 2 button switch where 1 is for the light and the other is for the fan.
Now that I'm thinking about this could it be the switch is not compatible?
What could be the cause of this and how to fix it

Did you use a meter to see if it has juice?

If it is just the LED bulbs that are not lighting. They are diodes, you might have to reverse the leads to make them work. Current has to go through a diode the right way to work. If the fan motor will not work it is probably not getting power. old243 It's both that are not firing up regardless if from the switches or the remote. There's a black and a white wire with a plastic connection from the motor to the lights and there's only 1 way to plug it in.

Try the wall switch in different spots and then remote. Just got off the phone with the manufacturer, they had me bypass the reciever same result. They had me remove the fan wire from the switch still nothing. The only thing left is the switch itself is bad. Who knows how old it is.

Use a meter to make sure you didn't lose a neutral X2 if you contact tester( you touch it to wire and it lights up) says it's hot it may be neautral , BUT takes very few volts to make them glow.

Neutral has 120. Pulled the pancake box no Knicks in the romex. Here's a few pics.

This is what I'm talking about. In any electric circuit you'll have source voltage at the beginning (in this case 120v), and 0v at the end of the circuit. The voltage.drops at each load. If there's only one load, all 120v drips across that load to 0v.....if the circuit is complete. That's the key. If the circuit isn't complete and there is an open (broken wire, open switch, etc) then the loads don't matter, it's as I'd they're not there. You'll have source voltage all the way up to the open, and 0v after that. Think of the "water in a pipe" analogy that's often used to describe electricity. Voltage is electrical pressure, equivalent to water pressure. In the pic below, you start out with 100psi. If the valve is open and water is flowing, you'll have 100psi before the load and 0psi after. If the valve is closed (equivalent to an open in an electrical circuit) you'll have100 psi before and after the load, all the way up to the valve, and 0psi after the valve. It's as if the load/restriction isn't there. It only matters if the water/current is flowing.

Open the switch box. Use your NCV to test for power. Find the correct breaker to kill the power. Remove the leads from the switch and wire nut them together... Constant power to the switch leg. Turn the power back on.
If fan works, the switch is bad. If it doesn't work then there is an issue elsewhere.
Those non-contact voltage testers are handy. But don't bet your life on one. If you are ever in a position that you have to touch wires and use an NCV, do a Live-Dead-Live test to make absolutely sure the NCV isn't lying to you.
